Classification of aluminum rods

1. According to the different content of alloying elements, aluminum sheets can be divided into: 1 ××× The series is industrial pure aluminum (Al), 2 ××× The series is made of aluminum copper alloy aluminum plate (Al Cu), 3 ××× The series is aluminum manganese alloy aluminum plate (Al Mn), 4 ××× The series is aluminum silicon alloy aluminum plate (Al Si), 5 ××× The series is aluminum magnesium alloy aluminum plate (Al Mg), 6 ××× The series is aluminum magnesium silicon alloy aluminum plate (AL Mg Si), 7 ××× The series is aluminum zinc alloy aluminum plate [AL -- Zn -- Mg -- (Cu)], 8 ××× It is composed of aluminum and other elements. Generally, each series should have three digits followed by a number or letter, meaning that the second digit represents the number of controlled impurities; The third and fourth digits represent the lowest percentage of pure aluminum content after the decimal point.
2. According to their appearance, they can be divided into round aluminum rods, square aluminum rods, hexagonal aluminum rods, trapezoidal aluminum rods, etc.
